Hello, Joachim. I think this is an NVIDIA driver issue, rather than an X.Org issue. Best to take this up on [email protected] rather than [email protected].
The NVIDIA driver does not presently have a way to specify which USB stereo emitter to use. That is a reasonable thing for us to add, though. In the mean time, unfortunately I cannot think of any good work arounds to suggest. Sorry, - Andy Ritger On Wed, 30 Jun 2010, [email protected] wrote:
Hi all, We have a number of workstations equipped w. Quadro FX 3800, 3D-Vision Stereo Glasses and Samsung 2233RZ 120 Hz Monitors. We are using OpenGL quad buffered Stereo under openSuSE LINUX 11.2 using the proprietary NVIDIA driver An attempt to equip the workstations with an additional set of the same Graphics Card, Monitors, Stereo Emitter, Keyboard and Mouse to realize a multiseat configuration however was not successful in respect to stereo display: We configured the computers essentially as shown in http://wpkg.org/Configuring_multiseat_X_workstation and this at a first glance seemed to work. Unfortunately the second seat configuration did not recognize the second USB Stereo Emitter and subsequently on this seat stereo was disabled. The error message in the Xorg.1.log was "Failed to claim USB interface for stereo emitter device. Disabling stereo" On the second stereo emitter the led was slowly blinking in red. On the other hand both Stereo-Emitters were listed in /proc/bus/usb/devices. Does anyone have a hint how to set the second stereo emitter into function? Regards, Joachim -- Dr. rer. nat.
